This invention relates to floor construction and particularly to a floor construction in which concrete beams are formed integral with the 'floor andthe spaces between said beams are closed by lath or other material suitable for the reception of plaster. a

One of the objects of the invention Vis to simplify the positioning of the inverte-d pans used in constructing such a. floor.

A further object of the invention is to provide a simple means for supporting the inverted pans and lath or the like, before, during and after pouring the concrete to form the floor and beams.

A further object of the invention is to provide a novel concrete floor which can be rapidly and cheaply laid and which shall be strong and durable and provide ample support for the ceiling and the plaster or the like applied thereto.

Other objects, advantages and capabilities will hereinafter more fully appear.

My invention further resides in the combination, construction and arrangements of parts illustrated in the accompanying drawings, and while I have shown herein a preferred embodiment I wish the same to be understood as illustrative only and not limiting the scope of my invention.

In the drawings:

Figure 1 is a broken perspective showing the construction of a floor according to my invention, and

Fig. 2 is a sectional elevation'thereof.

Referring to the drawings the numeral 1() designates sofits which are supported in suitable manner withtheir upper surfaces in the plane of the underside of the floor abouty to be laid, and occupying positions below the intended beams. Y

Upon said sofrit are applied longitudinally two parallel angle irons 11, each resting ona web 12 which is directed outwardly towards the edge of the board. The other web 13 is directed upwardly i-nto theV locationin which the beam is to be formed, the webs 13 of the pair of angle irons 11 upon a soft being preferably spaced apart somewhat less than the width of the bottom of such beam.

The v angle irons 11 are preferably formed from perforated lath metal, the perforations being designated la. The perforated web 13 becomes embedded in and'irmly held to the concrete of the beam. The webs 12 may be attached by nails 12', passed through the perforations thereof, to the sots. The perforations in the webs 12 enable the subsequently applied plaster to make firm bond therewith. l

Between adjacent sofit-s are laid sheets of lathing material 15 which may be metal lathing as shown in Fig. 1, or a board such as gypsum board, or celotex as shown in Fig. 2 or any other material which is adapted to receive plaster. The longitudinal edges of the'lathing material 15 rests upon webs 12 of the angle irons 11. It is preferred to shape the lathing material 15 soy that its under surface between theY angle irons 11, is in the plane of the under side of the webs 12 and the upper surface ofthe soits 10 so that after the floor is poured and set and the substructure removed,l the ceiling to kwhich plaster is to be applied lies in one plane.

For this purpose the main portion of the lathing material 15 may be dishedslightly with respect to v'its longitudinal edges, as shown in Fig.y 1, or said edges may be rab- -beted as shown in Fig, 2.

The pans 16 are applied so as to extend over thelathing material 15 and have their edges resting 'upon the lathing material 15 above the webs 12. r1`he distance between the edges ofthe pan 16 may suitably be slightly less than the distance between the webs 13 of theangle irons 11 on which they rest. If desired, said edges mayhave a snug fit with respect to the webs 13 and said edges of the pan 16 may be spaced aparta greater distance than that between the webs 13, the pan 16 being bent slightly in order to place same in extend transversely with respect to the beams and are located in the floor portieri of the concrete structure. rlhe concr to structure comprises beams 19 and floor :20 integral therewith.

It will be understood that when the concreto V"'ed 'to form the eans 19 and floor 20, the paas 16 resting npc 'lic lathing material i5, which in turn rests upon the webs 12 of the angle irons 11, eilectively prevent the escape of the concrete from the beam space. Said concrete surrounds Jthe webs 13 of the angle irons 11 and enters the openings L1 therein. so as to hold same firmly to the concrete beam 19. vaid concrete also envelops the reinforcing members 1T and 18 and produces a unitary structure of strength and rigidity. After the concrete has set, the sub-structure including the soiiits is removed leaving the ceiling ready for plastering.

I claim 1. A concrete door comprising integral concrete beams, inverted pans beneath said beams, a pair of angle irons in the ase of each beam, each angle iron having a web extending into the beam and firmly attached thereto and a horizontal web directed ontwardly therefrom, lathing material resting upon said webs and extending beneath said pans in the ceiling plane, said latliing being engaged between said pans and said horizontal webs.

9.. A concrete door comprisingr integral concrete beams, inverted pans between said beams, lathing material beneath said pans and receiving the edges thereof, angle irons supporting said lathing material and comprising a web extending` into the concrete beam and firmly secured thereto.

3. A concrete iioor comprising integral concrete beams, inverted pans between said beams, lathing material beneath said pans the edges of which rest upon the edges of the lathing material, angle irons having horizontal webs on which said edges of the lathing material rest, said angle irons having vertical perforated webs extending into and firmly embedded in the concrete thereof.

4. A concrete floor comprising reinforced integral concrete beams; inverted pans between said beams, lathing material beneath said pans and receiving the edges thereof, angle irons supporting said lathing material and comprising a web extendingr into the concrete beam and firmly secured thereto, said lathing material between said angle irons having its undersurface in the plane of the underside of the beams.`

5. Aconcrete floor comprising integral reinforced concrete beams, inverted pans between said beams, lathing material beneath said pans the edges of which rest upon the edges of the lathing material, angle irons having horizontal webs on which said edges of the lathing material rest, said angle irons
